The snows are alive. A soft, cold spirit courses through them. Her lace threads the world; watching, drinking, listening, stroking, soothing, killing. Her touch is soft and icy. She is Winterwhite, the daughter of the Waterdrinker and the Northwind, and she is a terrible god. An avatar of ice and hunger, of visions and death. Dooms and devastations to visit upon a cosy roleplaying setting. Longwinter is the RPG sandbox of a realm that has broken its vows to Winterwhite and will now pay the cold price. This book contains secret knowledge and mechanics for the referee.
